SPECIFICATION forming `part of Letters PatentiNo. 278,527, dated May 29, 1883.

` Application led February 19,` 1883. (No model.) i i To all whom it muy concern: l

Be it known that I, HENRY FLETCHER t se i SO.

. folk and State of New York, have invented a new and useful Improvement in Ice-Machine Cans, ot' which the following is a full, clear,

and exact description.

,Reference is to be had to the accompanying drawings, forming a part of this specitcation, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of my improvement. Fig. 2 is a sectional side elevation of the same, showing the core removed and the bottom cap secured in place. Fig. 3 is a bottom view of the can, andshowing in dotted lines the position of the bottom lange of the core. Fig. 4 is a sectional plan view of the c'an and core, taken through the liiie a: w, Fig. l. Fig. 5 is a plan view-of a block of ice. The object of this invention is to facilitate the freezing of blocks Lofice in ice-machines.

The invention consists in an ice-machine cauconstructed with a raised and apertured bottom, provided-withI a tlange and rubber pack.- iug around its aperture, and with bolts for se- `curingia core in the interior of the can, the

said core being provided with a ange and angu'lar packing-strips around its open bottom. The can is also provided with a caphaving an offset'with inclined shoulders for closing the aperturein the` can-bottom'wheu the core is removed, as will be hereinafter fully described.

A represents the brine-tank of an ice-machine, about the construction of which there is nothing new.

uB is the can in which the ice is frozen, and which has a flange, G, around its upper end to rest upon the top of the tank A, and suspend the said can in the said tank A.

D is the bottom of the can B, the edges ot' which are bent downward at right angles and rest against the walls ofthe said can.l The lower edges of the walls ofthe can B are bent the flanges of the bottom D, so that/the said bottom will be a little above the lower end. of

the said can-,B and will be securely supported. In `the center of the bottom D is formed a rectangular opening corresponding in shape to the p u shape of the can B, and tothe said bottom, atv a little distance from its inner edge, is attached l a iiange, .-E, forming an angular recess all l around the opening in the bottom D to form a seat for a rubber packing, F, Which'is made triangular in cross-section, as shown in Figs. 1 and 2, so as to have an inclined inner side.

G is the core, which is made with a closed upper end, except a small'opening, g, to allow the air to escape when the can is suspended in the-brine', and an open lower end, and of such a size as to pass through and fit into the open-` end of the core G is-formed a flange, H, and in the angle between the iiange H and the walls strip, I, the outer side ofwhich 'is inclined to rest and fit against the inclined surface of the packing F and form a closejoiut. In theends ofthe liange H are formed holes to receive the bolts J, attached to thecan-bottom D, so that the core G can be secured Ito the can B with a water-tight joint by screwing up hand-uutsK, `placed upon the bolts J. When the core Gis removed the opening in the can-bottom D is is made with an ol'set having inclined shoulders to lit against the packing F, the said oft die part of the cap [i will be in line with the bottom D, as showninn Fig. 2.

M is a core of the same shape and size as the core Gr, and which has a auge, N, around its open upper end to rest upon thetop ofthe brine-tank A and support'the said core when suspended in the said tank, as shown in Fig.].

In using myimprovemcnt the can B, with before described, is suspended in the brinetank A and supplied with water. which, as the brine circulates aroundthe can B and through thecore Gr, will be quickly frozen into ahollow block ot' ice. At the same timethe core M is suspended in the brine-tankA and supplied with water, so that the water in the said core will befrozen to form an ice core to fit into the interior ofthe hollow ice block frozen in the can B. When the water in the can B and core M isV frozen the can B is removed and inverted, and h ot `water is poured into the core G to loosen it, and the said core Gr is removed. The core M is removed from the tank and immersed in hot water to loosen it from ingin the'bottom D. Around the open lowerof'the core G is secured a triangular filling.

closed by a cap, L, the middle part of which set being made of such a depth that the lnidi the core G secured init in the manner hereinv ICO the block of ice, and the said ice block is re moved and inserted in the interior of the block of ice in the can B. The cap L is then secured to the bottom of the can B in the manner hereinloetore described, and the can B is again suspeudedin the brine-tank A, and wateris poured into the space around the ice core, so that the hollowice block and theice core Willbe quickly frozen together, forming a solid block of ice, which can then be' removed from the can.

With this improvement ice can be formed more quickly in larger blocks and of better quality than is practicable when the Water is frozen Wholly from the outer sides ofthe cans.

I am aware that it is not new to form aniceinold with upwardly-projecting top-closed and.

I frozen; but

AW'hat I do claim as new and of my invention is 1, The combination, with the can B, having raised and apertured bottom D," provided with ange E, rubber packing F, and bolts J, of the core G, having an open bottom provided with ange H and filling-strip I, substantially as herein shown and described, whereby the said core will be rmly held and can be readily inserted and removed, asset forth.

2. The combination, with the can B, having raised and apertured bottom D, provided-With the ange E, rubber packing F, and bolts J, ofthe cap ]J,l1avin,g` offset with inclined shoulders, substantiall y as herein shown and described, whereby the aperture in the can-bot- 35 tom can be readily and securely closed, as set forth.
